Am I reading the sizing right? If I wear a US size 9 shoe then does that mean size L/XL?
The sizing chart is way off. I got the XXL to go on my 10.5-11 feet. The socks were way huge. The L/XL fit exactly.
I'm a US 9.5/10, I bought the L/XL and the heel cup marking (where sock is different color at heel) ends up covering my Achilles tendon when pulled up tight enough to prevent bunching around my toes. I bought the Medium and had a perfect fit.
Castelli is bizarre fit wise. Socks are typically much larger and shorts/jerseys much smaller. I'm a huge Castelli fan, just takes trial and error trying to get the best fit. Don't get me started on the way Castelli full zip jerseys vs. 1/2 zip jerseys fit....
